…10 (chartjs#5275) * Bugfix: Improve polyfill function of log10 to return whole powers of 10 as integer values, as it caused endless loop in IE11 in the tick creation loop. * Compare floating-point numbers directly instead of using unnecessary division.

The
helpers.log10polyfill function doesn't return precise integer values for all whole powers of 10.This can cause an infinite loop as issued in #5264
The proposed PR uses a multiplication with
Math.LOG10Einstead of a division byMath.LN10. This improves the accuracy, however as is shown in the table below, not all computed powers are correct, thus leading to the extra check, which is slower, but more accurate.
